Ansamitocin P3 (66547-09-9) is a fungal metabolite from Actinosynnema pretiosum which binds to the phomopsin A/rhizoxin site on tubulin.1,2 Ansamitocin P3 is a maytansine analog which displays potent cytotoxicity...

Colchicine (64-86-8) is a naturally occurring alkaloid which acts as an antimitotic agent by binding to tubulin and depolymerizing microtubules. Colchicine induces apoptosis in a variety of cell lines...

Cytochalasin D (22144-77-0) is a potent inhibitor of actin polymerization which also causes the disruption of actin filaments. More potent that cytochalasin B (10-fold) and does not inhibit monosaccharide transport across...

K-858 (72926-24-0) is a selective mitotic kinesin Eg5 inhibitor (IC50 = 1.3 μM) which acts in an ATP-noncompetitive manner1,2. It is at least 150-fold more selective for Eg5 than other members of the kinesin superfamily...

Monastrol (254753-54-3) is a potent, cell-permeable, small molecule inhibitor of mitosis. Monastrol-arrested cells are characterized by monopolar spindles.1 Does not affect other motor proteins or tubulin. Specifically...

Nocodazole (31430-18-9) is an antimitotic agent that disrupts microtubules by binding to β tubulin and thereby inhibiting microtubule dynamics, disruption of mitotic spindle function, and fragmentation of the Golgi...
